Timber is like that too. I spray him all the time, but a couple of times a month, usually after I spray him, he will go stick his head in his water bowl. That is my signal to get the dish and he dives right in.
So glad to hear that Gilbert weathered the trip so well I can't get over how much progress Gilbert has made in the last few months. Moral of the story... never give up
Hello and welcome David and Luna Post some pics so we can see your girl. I'm a novice so more experienced members will address your step up questions, but my thought is that it is early days yet and Luna will learn to step up on your hand or the perch as time passes.
